Just a followup. I did ask for the v20028 firmware and they sent me the link. I upgraded the firmware on the RM Pro and I was able to download Tuice's L codes and see them being sent. I tried several times to try and learn new codes both regular and security rf but saying it was difficult is being nice. Maybe one out of several to a dozen would finally learn. But then even after it said it was successful it would not send the command. So I waited for the different one on ordered.
The new unit arrived yesterday. It's a RM Pro+. I set it up in the econtrol app and tried to learn my first security code. Bingo, first try and it was successful. Second button successful 1st try. 3rd button successful 1st try. So I now have Arm-Home, Arm-Away and Disarm all configured in the econtrol app. Now to move on and get it setup in HA.
